CONSTRITCTION' 01E WAGON AND LIKE TANK S.

Application filed August 4, 1927, Serial No. 310,472, and in Great Britain May 7, 1927.

This invention relates to wagon and like tanks and more particularly wagon tanks such as. are used for the conveyance of petrol, paraffimoils and other liquids usually mounted upon road lorries, steam lorries, carts and the'like, and has for object to pro vide improvements therein.

A tank made according to the present invention is provided with corrugations of any type, design or distance apart rolled or pressed circumferentially, longitudinally, diagonally or otherwise, to stiffen and strengthen the body.

Further, according to the present inven tion the end and/or the division plates of the tank may be embossedor corrugated vertically, horizontally, annularly or with a suitable pattern. V

The corrugations may be internal and in this case provision may be made for. completely draining the tank.

and consequently maintaining unimpaired the strength and rigidity of the tank.

The tanks may be cylindrical, -D-shaped or'of other suitable'form.-

Tanks made according to the present invention are illustrated, by way of. example, in the accompanying drawings, wherein,

oval,

vation respectively, a cylindrical single compartment-tank, with external corrugations;

Figs. 3 and 4 show, infront and end elevation respectively, a D-shaped triple compartment tank, with internal corrugations;

Figs. 5 and 6 are detail views illustrating a suitable draining arrangement for use in tanks provided with internal corrugations.

Referring to Figs. 1 and 2, thebody a of the tank is provided with external corrugations I) rolled or pressed circumferentially. The end plates 0 are embossed or corrugated in horizontal lines (5.

In Figs. 8 and 4 the corrugations b are internal, and the end plates 0 are corrugated or embossed in'vertical lines The division plates g are corrugatedin the same way as the end plates 0.

The draining arrangement shown in Figs.

A suitable way of draining the tank consists in cuttinggried, with any given total load. I

such tanks have been made of steel plates Figs. 1 and 2 show, in front, and end eie- 5 and 6 is suitable for use in the tank shown in Figs. 3 and 4. In Figs. 5 and 6, it, h are the draining slots and 7c is a plate welded over the said slots. Figs. 5 and 6 show holes through the strengthening ribs or corrugations through which the liquid may flow to the outlet ofthe tank to prevent retention of liquid between the ribs of the tank which lie at the bottom. This allows the tank to be completely emptied, which would otherwise be very difficult. Thus the. holes permit of communication bet-ween the channels between successive ribsand thus theopenings ofcthe corrugations are for the purpose of allowing the liquid trapped be tween the corrugations to" flow towards a spigot provided at a suitable place, for eX-.

show circumferential outside or inside corrugations it is provided that the em'bossings or corrugations may run as shown or longitudinally, diagonally or otherwise, and the ends or divisions may be strengthened by vertlcal, horizontal, or annular corrugations,-or with any suitablepattern.

The combined weight of the tank and its fittings and the liquidv contents thereof form,

the total load on the vehicle, and thus the lighter the weight of the tank the greater is the weight of liquid which can be car- Hitherto varying from t to but by the use of sheets may be used thus increasing theleflicientload of the vehicle, whilst at the same this invention very much thinnermetal' 2. A wagon tank of curvilinear outline in cross section comprising vertical corrugations, adrainage device thereto, and a cover plate to said dralnage device.

In testimony whereof, I afiix mysignature.' I
